Drought effects in Mediterranean forests are not alleviated by diversity‐driven water source partitioning

open access: yesJournal of Ecology, Volume 112, Issue 9, Page 2107-2122, September 2024.
Tree species diversity promotes below‐ground water source partitioning in mixed oak and pine stands, potentially reducing competition for water in more diverse ecosystems. Yet, these results show that it is insufficient to buffer the adverse impacts of severe droughts on above‐ground tree carbon and water use, leading to higher water stress, especially

Comparing carbon offsets and livelihood benefits in a long‐term reforestation project: Agroforestry versus native timber versus enrichment planting

open access: yesEcological Solutions and Evidence, Volume 5, Issue 3, July–September 2024.
Looking at different reforestation methods over 14 years in an Emberá Indigenous community in Panama we found that plots with native timber mixtures and monocultures stored three times more carbon than those with agroforestry or natural regrowth. Natural regrowth was less valued by participants due to the abundance of pioneer species, but it helped ...
